Fast command-line tool to upload a directory to an AWS S3 bucket and optionally invalidate the associated AWS CloudFront distribution. By default all uploaded files will be public. Per bucket caching is done in local .s3front.json file to avoid uploading the same file.

The content of website_dir will be uploaded to the S3 bucket named website.
If the upload is successful and a distribution containing an alias website is found, the whole distribution will be invalidated.
